QPHY-10GBASE-T Operator’s Manual
In the previous procedure, we used the default setup of the Skew parameter (which is detecting
positive edges on both signals at 50%). We also inverted C2 in order to make C1 and C2 both
have positive edges at the same time.
Alternately, we clearly could have not inverted C2 and instead selected the Skew clock 2 tab in
the P1 parameter menu and set the oscilloscope to look for negative edges on the second input
(C2). However, we believe that the previous procedure looks much more aesthetically pleasing
from the display as it shows C2 and C3 with the same polarity.
